public class ToolPalette

extends CanvasPalette

Although there are multiple ways a DrawingCanvas can get its tool(s), a typical approach is providing a palette from which to choose them. This class provides a very simple version of one. There is obviously room for improvement (e.g. tool tips, etc.). NOTE: Right now, the layout managers are kind of mixed up. They should all be standardized (probably to GridBag) and tested to ensure that icons and labels can be interchanged and still look good.
